The purpose of this utility model is achieved by the following technical solution:

The utility model is mainly by casing inner blower, combustion gas, combustion head, combustion tube, smoke collecting chamber, heat exchanger, and air-introduced machine and air supply duct, evaporation coil, peripheral hardware condenser constitute.

Casing is formed by the hardware assembly welding, is divided into upper and lower chamber by central dividing plate in the casing.Bottom chamber is installing blower fan and control cabinet thereof, and the blower fan exhaust outlet leads to upper chamber.Upper chamber is divided into forward and backward chamber by vertical dividing plate.Vertical dividing plate one side (front chamber in) is installed with combustion head and gas valve thereof, ignition, and air-introduced machine is being adorned in its top, and the exhaust outlet of air-introduced machine is outside casing.The opposite side (in the rear chamber) of vertical dividing plate is installed with several L shaped combustion tubes that connect combustion head, its other end is communicated with the rectangular set smoke chamber, this top, group chamber is communicated with some S shape tubing heat exchangers side by side, and the other end connected set smoke box of this heat exchanger leads to the air-introduced machine air inlet.

On the casing of corresponding rear chamber air supply duct is installed, its import department is equipped with evaporation coil, and this evaporation coil is linked to each other with the condenser of peripheral hardware by tube connector, and air supply duct leads to the room that needs heating and air-conditioning.

Application process of the present utility model is: cold season in winter, start blower fan by control cabinet and blow in rear chamber; Ignition is lighted each combustion head, and the burned in succession pipe of the heat energy in gas flame and the hot flue gas, smoke collecting chamber, heat exchanger absorb; With heating back cavity room air, fan airflow is sent into the room heating with hot-air through air supply duct continuously.

Hot season in summer, combustion head is stopped using, and starts blower fan and condenser, and condenser causes the evaporation coil in the pipeline, cooling surrounding air, and fan airflow is sent into cold air the room refrigeration air-conditioner continuously.

The utility model can be used as the room ventilation ventilator and uses if only start blower fan, to regulate room air.

The utility model distinguishing feature is

1, because combustion gas (natural gas, coal gas, liquefied gas) belongs to clean fuel, can significantly reduce pollution to atmospheric environment.

2, owing to adopt air to make heating agent, can significantly reduce water consumption, the conserve water resource.

3, utilize air-flow heating and air-conditioning can strengthen the room air circulation, with fresh air in the holding chamber, be of value to health.

4, dual-use, heat supply in winter, summer air-conditioning, ventilation, and can be embodied as heating of a plurality of rooms and air-conditioning easily, air supply duct is installed.Than hot-water heating simple equipments, small investment are installed, help applying.
